La persistenza della memoria

This volume compiles the proceedings of the IX Gregorian Days, establishing an interdisciplinary framework for the study, protection, and enhancement of historical landscapes. Grounded in the European Landscape Convention and public archaeology principles, the collected research explores the integration of material and immaterial heritage within territorial identity. The papers examine the epistemological role of art as a historical source for interpreting past environments, the application of digital technologies—such as mobile apps, 3D modeling, and augmented reality—for immersive heritage communication, and innovative landscape planning approaches like Sicily's Agri Gentium project. By bridging academic inquiry with active community engagement, the work demonstrates how sustainable management, historical continuity, and participatory methodologies transform cultural assets into dynamic drivers of regional development. Ultimately, the publication underscores the evolving relationship between natural environments, human memory, and contemporary spatial governance.
